All good, those, just different. I'd like one of those Bessas, myself.
Like Douglas, I'd probably prefer an OM-2, for general use, though I don't quite recall why. (I seriously-considered jumping from Canon FD to Olympus when I was young, though. I also liked one of the more-modern ones, that wasn't the OM-4, but had spot metering and possibly a program mode I couldn't have cared less about
: I don't recall if those qualities were on the same model and I also don't know how time has treated them. Possibly one of the OM-2 updates. Ask some Olympians, there.
)
Anyway, all good choices. Lens availability for the Olympus may be at issue: make sure you can get what you need. They made an excellent 40, which always endears a brand to me, but I don't know how many are out there.
